Overview

The Electrocorder EC-2VA is a single-phase voltage, current, power and energy logger for load studies, voltage/current investigations and energy monitoring where flexible current sensing is useful.

Use it when you need to understand how a single-phase circuit or item of equipment behaves over time, including whether low voltage is linked to high current demand. The EC-2VA combines a voltage connection with a flexible Rogowski current sensor, making it useful where conductors are larger or where a split flexible coil is easier to fit.

Best for:

• Single-phase power and energy monitoring.
• Investigating whether voltage problems are related to current demand.
• Load surveys on circuits where a flexible Rogowski coil is easier to fit.
• Energy audits and consumption checks on single-phase loads.
• Temporary monitoring where power and energy values are needed, not just voltage.

Consider another model if:

• You need a clamp-on CT rather than a flexible coil, where the CT-2VA may be simpler.
• You need plug-in appliance monitoring, where the AL-2VA may be easier to use.
• You need three-phase power and power factor, where the EC-7VAR-RS is more appropriate.

What you get:

• EC-2VA logger.
• Flexible Rogowski current sensor, voltage input lead, USB lead, carry case, batteries, user instructions and free Electrosoft analysis software.
• A detachable-coil system that can support different physical coil sizes where required.

Set up the logger in Electrosoft, connect the voltage lead and fit the Rogowski coil around the conductor being monitored, then start recording. When enough data has been captured, connect the logger to a PC by USB and use Electrosoft to view, save, export and report on the results.

Applications

Typical applications: The EC-2VA is intended for single-phase power and energy investigations where voltage and current need to be understood together.

What the EC-2VA records:

• Single-phase voltage and current.
• Power and energy values derived from the voltage and current measurements.
• Minimum, maximum and true average values over the selected averaging period.
• Data for checking whether voltage changes are related to current demand.

Why constant sampling matters: many instruments only take periodic snapshots. The Electrocorder continuously samples throughout the averaging period, helping capture short events, changing loads and trend data that can otherwise be missed.

Recording duration depends on the selected averaging period. Longer periods support energy-use monitoring, while shorter periods can be used for more detailed investigations.

The logger is typically fitted by a competent person at a distribution board, meter board or suitable test point. The Rogowski coil opens at the joint so it can be placed around a conductor without breaking the main circuit.

Features

When to choose the EC-2VA
Choose this model when the investigation needs single-phase voltage, current, power and energy data and a flexible current sensor is useful.

Compare with related Electrocorder models
If a clamp-on CT is a better physical fit, consider the CT-2VA. If the load plugs into a standard socket, consider the AL-2VA. For three-phase systems, consider the EC-7VAR-RS.

Key features:

• Records single-phase voltage and current together.
• Flexible Rogowski coil can fit around larger conductors.
• Useful for energy monitoring, voltage/current correlation and load studies.
• Detachable coil arrangement allows coil changes where supported.
• Constant sampling to reduce the risk of missing short-duration or changing load events.

Measurement note
Because the EC-2VA measures voltage and current together, it can support power and energy analysis. It should be installed by a competent person where access to conductors or distribution equipment is required.

FAQ

What is the EC-2VA used for?
It is used for single-phase voltage, current, power and energy monitoring.

Why choose a Rogowski coil?
A Rogowski coil is flexible and can be easier to fit around larger conductors or awkward cable arrangements.

How is it different from CT-2VA?
The EC-2VA uses a flexible Rogowski coil. The CT-2VA uses a clamp-on current transformer.

Can it show whether low voltage is linked to high current demand?
Yes. Because it records voltage and current together, it can help compare voltage behaviour with load demand.

What software is used to analyse the data?
Electrosoft PC software is used to configure the logger, download recorded data, view graphs, export data and create reports.
